hi my daughter is 4 month old she is on formula milk just because I have a milk issue should I give give her cow milk and formula milk both ???

A. hi dear 4 months old: 6 ounces (180 mL) per feeding. 6 months old: 7-8 ounces (210-240 mL) per feeding. The amount can vary depending on the baby's weight and if the baby is going through a growth spurt. ... The most amount of formula advised per day is 32 ounces (1 liter).
